An electronics manufacturing process has historically had a mean completion time of 70 minutes. It is claimed that, due to improvements in the process, the mean completion time, u is now < 70minutes. A random sample of 10 completion times using the new process is taken. The sample has a mean completion time of 63 minutes, with a standard deviation of 11 minutes. Assume that completion times using the new process are approximately normally distributes. At the 0.10 level of significance, can it be concluded that the population mean completion time using the new process is < 70 minutes? a) state the null hypothesis H0 and the alternative hypothesis H1. H0= H1= b) determine the type of test statistic to use. c) Find the value of the test statistic d) Find the P value. e) can it be concluded that the mean completion time using the new process is < 70 minutes? y or n
